(Tcl) WPA Key Calculation from PassPhrase to Hex
Demonstrates how to calculate a WPA key from a passprhase and network SSID.
load ./chilkat.dll
# This example assumes the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.
set crypt [new_CkCrypt2]
# The "ps" is the WPA passphrase
set pw "password"
set pwCharset "ansi"
# Hash algorithms may be: sha1, md2, md5, etc.
set hashAlg "sha1"
# Specify the SSID in hex:
# For example, if the SSID is "ABC", then the
# hex values for these us-ascii chars is "414243"
set ssidHex "414243"
# The WPA key calculation will always use 4096 iterations.
set iterationCount 4096
# The WPA hex output should be 256 bits.
set outputBitLen 256
# Indicate that "hex" is to be returned.
set enc "hex"
set wpaHexKey [CkCrypt2_pbkdf2 $crypt $pw $pwCharset $hashAlg $ssidHex $iterationCount $outputBitLen $enc]
puts "$wpaHexKey"
